Q1
The clock input (from OSC1) is internally divided by four to generate four non-overlapping
quadrature clocks, namely Q1, Q2, Q3, and Q4. Internally, the program counter (PC) is incre-
mented every Q1, and the instruction is fetched from the program memory and latched into the
instruction register in Q4. The instruction is decoded and executed during the following Q1
through Q4. The clocks and instruction execution flow are illustrated in
